Abstract
Abstract A safety cover for preventing access to an electrical receptacle while the receptacle contains a plug includes a receiving plate and a box-shaped cover assembly which can be locked over the receiving plate. The cover assembly has a plurality of locking flanges each of which can be independently depressed and thereby moved in and out of means for receiving locking flanges located on the receiving plate. To remove the cover assembly from the receiving plate, it is necessary to simultaneously depress each locking flange. Flange-releasing means are positioned on the cover assembly in a manner that renders small children incapable of reaching and depressing all the flanges simultaneously.
